所以這裏是我爲您工作的解決方案!
當然,您必須用您的FTP服務器的rootURL替換「root」的值,並在方法GetWebRequest()中用您的憑證替換「用戶名」和「密碼」!
你需要這個類來保存詳細
public class FTPListDetail
{
public bool IsDirectory
{
get
{
return !string.IsNullOrWhiteSpace(Dir) && Dir.ToLower().Equals("d");
}
}
internal string Dir { get; set; }
public string Permission { get; set; }
public string Filecode { get; set; }
public string Owner { get; set; }
public string Group { get; set; }
public string Name { get; set; }
public string FullPath { get; set; }
}
,這裏是代碼隱藏您的WinForm程序內置
private void button1_Click(object sender, EventArgs e)
{
var root = "ftp://ftp.yourFTPServer.at";
treeView1.Nodes.Clear();
treeView1.Nodes.Add(CreateDirectoryNode(root, "root"));
}
private TreeNode CreateDirectoryNode(string path, string name)
{
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);
var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);
foreach (var dir in directories)
{
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name));
}
foreach (var file in files)
{
directoryNode.Nodes.Add(new TreeNode(file.Name));
}
return directoryNode;
}
public IEnumerable<FTPListDetail> GetDirectoryListing(string rootUri)
{
var CurrentRemoteDirectory = rootUri;
var result = new StringBuilder();
var request = GetWebRequest(WebRequestMethods.Ftp.ListDirectoryDetails, CurrentRemoteDirectory);
using (var response = request.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
string line = reader.ReadLine();
while (line != null)
{
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}
if (string.IsNullOrEmpty(result.ToString()))
{
return new List<FTPListDetail>();
}
result.Remove(result.ToString().LastIndexOf("\n"), 1);
var results = result.ToString().Split('\n');
string regex =
@"^" + //# Start of line
@"(?<dir>[\-ld])" + //# File size

你使用哪種TECHNOLOGIE? ASP.NET,WPF,WinForms?和哪個TreeView? – makim
它的WinForms,和它的正常TreeView與節點旁邊的加號 –
好吧我會看看,並會發表一個答案;-) – makim
